ABSTRACT OF THE DISCLOSURE A safety hook comprising a curved hook body provided with a hook opening defined by a substantially U-shaped part and pivotally connected to a hook head which carries a pivotal shackle device, wherein the hook body, in a first, open, position, is held swung relative to the hook head so as to leave the hook opening open and therewith enable a load to be hooked onto the hook body, and wherein the hook body, in a second, closed, position, is swung relative to the hook head such that the hook opening is blocked my means of a barrier part which projects outwardly from the hook head, and wherein latching devices are provided for releasably securing the hook body essentially in the second position. The hook is mainly characterized in that the hook body is held in the first position by a spring force, in that the weight distribution on the hook is such that the opening defined by the U-shaped part is essentially horizontal in a vertical plane when the hook hangs substantially freely with no load thereon, and in that when the U-shaped part is subjected to a downwardly acting load, the U-shaped part is swung against a spring force towards and to the second, closed position, the spring force striving to return the hook body to the first position.
